本文實(shí)例為大家分享了Android實(shí)現(xiàn)觸摸移動(dòng)的懸浮窗的具體代碼，供大家參考，具體內(nèi)容如下

1.觸摸移動(dòng)的懸浮窗的快速實(shí)現(xiàn) UI
2. 懸浮窗實(shí)現(xiàn)
2.1 懸浮窗權(quán)限
為了偷懶，我SDK選擇比較低的17，如果不配置權(quán)限，則應(yīng)用會(huì)運(yùn)行報(bào)錯(cuò)
正規(guī)流程，查詢是否有懸浮窗權(quán)限，如果沒有需要提示，并跳轉(zhuǎn)到懸浮窗設(shè)置界面“即是否允許運(yùn)行在其他應(yīng)用上面”
2.2 懸浮窗配置初始化
這里主要關(guān)注 mParams.type 和 mParams.flags 這兩個(gè)參數(shù)是核心，我們也可以使用View來加載一個(gè)布局，為了側(cè)重懸浮窗界面，我直接使用TextView演示

private void initFloatWindow() {
if (mShow == null) {
mWm = (WindowManager) getSystemService(Context.WINDOW_SERVICE);
mShow = new TextView(this);
mShow.setText("I Love You");
mShow.setTextColor(Color.RED);
mShow.setTextSize(50);
mShow.setOnTouchListener(new View.OnTouchListener() {
int lastX = 0;
int lastY = 0;
int paramX = 0;
int paramY = 0;
@Override
public boolean onTouch(View view, MotionEvent motionEvent) {
switch (motionEvent.getAction()) {
case MotionEvent.ACTION_DOWN:
lastX = (int) motionEvent.getRawX();
lastY = (int) motionEvent.getRawY();
paramX = mParams.x;
paramY = mParams.y;
break;
case MotionEvent.ACTION_MOVE:
int dx = (int) motionEvent.getRawX() - lastX;
int dy = (int) motionEvent.getRawY() - lastY;
mParams.x = paramX + dx;
mParams.y = paramY + dy;
mWm.updateViewLayout(mShow, mParams);
break;
}
return true;
}
});
mParams = new WindowManager.LayoutParams();
mParams.width = WindowManager.LayoutParams.WRAP_CONTENT;
mParams.height = WindowManager.LayoutParams.WRAP_CONTENT;
mParams.type = WindowManager.LayoutParams.TYPE_SYSTEM_ALERT;
// 實(shí)現(xiàn)懸浮窗可以移動(dòng)的屬性
mParams.flags = WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE;
mParams.format = PixelFormat.TRANSPARENT;
}
}2.3 懸浮窗顯示
mWm.addView(mShow, mParams);
2.4 懸浮窗隱藏
mWm.removeView(mShow);
